Metalworking chisel GRAPHITE 57H551 — weight 1.91 kg, single piece

GRAPHITE 57H551 is a single-piece metalworking spade chisel designed for heavy-duty manual and powered use. With a weight of 1.91 kg, a 100 mm thick spade and a total length of 450 mm, this SDS‑Max chisel is suited to cutting, chipping and digging in concrete, hollow blocks, bricks and stone. It is commonly used for demolition, chasing piping and wiring furrows in walls, and for excavation in compacted ground during renovation and construction work.

Advantages

The SDS‑Max connection provides secure mounting in compatible rotary hammers and breakers, enabling efficient power cutting and longer tool life. The spade point geometry concentrates impact force for high performance in material removal and digging. Supplied as a single piece in a hanging polybag with sticker, the tool is robust enough for repeated use in indoor renovation, conversion and general construction tasks.

How to use

Install the chisel into a compatible SDS‑Max rotary hammer or breaker following the tool manufacturer's instructions and ensure the connection locks securely. Position the spade point on the work surface to concentrate impacts where material removal is required. Use controlled striking and progressive passes rather than forcing the tool; allow the power tool and chisel geometry to remove material effectively. Wear appropriate personal protective equipment including eye, ear and hand protection, and ensure bystanders are clear of the work area.

Usage recommendations

For best results, use the GRAPHITE 57H551 with a rotary hammer designed for SDS‑Max bits that matches the intended job size and power output. Keep the chisel clean of debris and inspect for damage before use; replace the tool if the spade edge is severely worn or the shank is deformed. When chasing furrows, work in short passes and remove debris frequently to prevent binding.
